To be fair, CCleaner is a very thorough and powerful end-user tool. Dave Cowen used it as an example in his anti-anti-forensics talk -- related to his $Logfile research. It's not just a joke. And, as Harlan points out, it's easy enough to test, which is what Dave did.

Sure it is , still it is not aimed at secure erasing a device, it is aimed to erase a filesystem or, more correctly parts of the filesystem (files or free space or even unused/old $MFT entries), just like Recuva is aimed to recover deleted files on a filesystem:www.piriform.com/docs/...r-settings

In my perverted mind, if all I can find, with *whatever* methods, on *any* sector of the device is 00's then that is "secure erase", and most if not all "secure erase" programs are aimed to the device and not at the filesystem, so I wouldn't know with what to compare, possibly sdelete:technet.microsoft.com/...97443.aspx
